Backup FAILED
无法创建 'D:test20140914193220.zip'
文件名、目录名或卷标语法不正确。

Answer 1

zip_command = " rar a '%s' %s" % (target, ' '.join(source))

试试改成

zip_command = " rar a %s %s" % (target, ' '.join(source))

Answer 2

import os

import time

source = 'C:\Intel\Logs\23.txt'

target_dir = 'e:\backup\'

today = target_dir + time.strftime('%Y%m%d')

#print (today)

now = time.strftime('%H%M%S')

comment = input('Enger a comment--->::::')

print (comment)

if len(comment) ==0:

    target = today + os.sep + now + '.zip'

    #print (target)

else:

    target = today + os.sep + now + '_' + comment.replace(' ', '_') + '.zip'

    #rint (target)

if not os.path.exists(today):

    os.mkdir(today)

    print ("Sucessful mkdir directory")

#print (os.sep)

#target = today + os.sep + now + '.zip'

#print (target)

zip_command = "makecab %s %s" % (source,target)

#print (zip_command)

if os.system(zip_command) == 0:

    print ('Sucessful backup to' ,target)

else:

    print ('Backup faild!')

Answer 3

import os

import time

 

source = 'C:\test'

target_dir = 'D:\test'

today = target_dir + os.sep + time.strftime('%Y%m%d')

now = time.strftime('%H%M%S')

target = today + '_' + now + '.zip'

zip_command = "rar a %s %s" %(target, source)

if os.system(zip_command) == 0:

    print ("Successful backup to " + target)

else:

    print ("Backup FAILED") 

Answer 4

    today = target_dir + time.strftime('%Y%m')

TypeError: can only concatenate list (not "str") to list

Answer 5

C:\test

Answer 6

你先创建一下test20140914目录，再输出压缩文件试试。

这个问题其实跟python没多大关系。
